61 Calculates a SHAKE128 digest (FIPS 202) with a security of math.min(128, math.log(#output_alphabet, 2) * output_length/2) for collision attacks and math.min(128, math.log(#output_alphabet, 2) * output_length) for preimage and second preimage attacks. If #output_alphabet is a power of 2, a direct base-N encoding is performed. Otherwise, a base-N encoding with N equal to the next higher power of 2 is performed, and all character values smaller than or equal to #output_alphabet are discarded from the stream (the process is repeated until the hash length reaches the required output_length).
